It seems there's a decent amount of overlap between INFJs and ISFJs. I stumbled across some ISFJ posts today, which spurred me to look into things a bit further, and while the descriptions for INFJ have always really leaped off the page for me, there are some Si ISFJ characteristic that I think I might recognize in myself as well.
I know the bulk of it is Ni vs Si, but the more I read, the more I am doubting my grasp of a few of functions, Ni being one of them. The idea of Ni being convergent vs Ne being divergent is a bit confusing to me. I get the concepts of convergence and divergence, but am looking for more examples to make it stick.
So, in your experience or theory, what are the real dividing characteristics between these two types?
